I assume you are talking about the 8mm Mauser, not the 8mm Remington
Magnum or the 8x60R Kropatschek. Caliber is only one part of a
cartridge. The 8mm Mauser, or 8x57JS, was the German WWII military
round. It is pretty comparable to .30-06, and was the round that forced
the USA to develop the .30-06. Check for ammo availability in your area.
If local stores carry a good assortment of ammunition, it could be a
satisfactory choice. Your selection of bullets will not be as wide as
for the .308 (same as the .30-06), but you should find something that
will get the job done for deer. American factory Mauser loads tend to be
a bit anemic compared to the .30-06, so you will have to buy European
loads. If you reload, and have a sound Model 98, the problem disappears.
Check http://www.chuckhawks.com/8mm.htm for a good article.
Check the gun carefully. If it is a sporterized surplus Mauser,
which I assume from the price, examine the bolt handle with the bolt
open. The bolt handle may not clear a scope, even if the handle is bent
style. Also, check head space, which is how tightly the shoulder of the
cartridge fits the chamber. Take a factory round, add three layers of
scotch tape to the shoulder of the cartridge and try to chamber it. If
the cartridge will chamber without forcing, the head space needs
adjusted. If the serial numbers on the receiver and bolt don't match,
you are almost guaranteed a headspace problem, unless it has already been
repaired.
If this is a sporterized Mauser 98, the rifle itself is an excellent
design. The value of the gun pretty much depends on the quality and
thoroughness of the gunsmithing. What sights were mounted? Was it
drilled and tapped for scope rings? Does it have a lot of trigger creep?
Judging the value is up to you, since you didn't even say what kind of
rifle it was.
I hand load. That makes the 30-06 slightly more powerful than 8mm for
light bullets, and both slightly more powerful than the .308 with all
weight bullets.
Still, there is not enough difference between any of them in
performance, noise, or recoil to notice.
For elk at extreme ranges, the next step up that matters is the 300 Win
mag. It noticeably does shoot further, make more noise, and kick harder.
But for factory ammo, there are some real wimpy 8mm loads being sold in
the US. If I didn't handload, I would avoid the 8mm in favor of the .308
or 30-06.
As for the 8mm magnum, its in between a .300 magnum and a .338 magnum,
and ammunition is extremely hard to find.
Assuming it is an 8x57 mm (ie Mauser) it is straining to reach the power
level of the 06. Factory loads WILL NOT get it there. Handloads or the newer
"magnum" loads for std calibers will. Judging by the question, I'm assuming
you will be buying factory loads as you aren't "into" rifles enough to be
handloading at this time. The 8x57 has very few choices in factory loads,
they will work though. With moose in the picture, just get an 06.

I have a savage 30.06 w/a 8X32 scope and case for 350 USD :-). If that
helps, ) I do not know about the xchange rate today).

The difference is a whopping 0.015" -- 0.308" vs 0.323". Power, if
we're talking Mauser vs 308, is within a frog's hair of being the same
with a reasonable load.

As others have mentioned, the 8 X 57 is plenty for deer and moose. Very close in capabilities to the .30-06 however factory loads are kept low due to many variations and conditions of the surplus weapons. Let's remember that Weatherby based all of his first high power rifles on the M98 action. If the one you are looking at is a M98 in good shape it is likely plenty strong for some fairly heavy loads.
