Looking for an inexpensive Video Switcher

[Argo22]

I am in the market for a new or used video switcher. I would like
something inexpensive, if there is such a thing. I have looked at
Videonics MX-1, MX-Pro, etc. but I cannot work with the video delay
between switches.. I have seen some datavideo products such as the
SE-500 which seem nice, but I cannot find much information about them.
Do these switchers have a delay like the videonics as well? Also, any
others to look at? I have seen edirol and others but $2000+ is not
really in my price range at the moment. Looking for either new or used
anything $0 - $1000 or so.

I currently have a Panasonic WJ-MX12, but i am running into
limitations now as it only has 2 inputs and no real overlay except for
luma. I do like the ability to have basic audio controls in it
though.

Any information would be great.

Thanks
