I Debated and Priced the same scenario last year and here's what I wound up doing.
I bought a 2nd Brennan B2 (new). SD Card version 240gb for around $400+. I Rip on it exclusively now and will be putting a new 1TB SD Card ($200) in it eventually. Brennans also make great little Network Servers so here's what I gained with the new B2 purchase;
1- New Integrated CD Ripping mechanism/workstation
(Allowing me to multitask - Ripping and ART retrieval on new #2, Editing on #1). Its also great to have a spare as a Production backup.
1- New Network Server allowing me to further Segregate my 10,000 CD collection (storing Christmas & other Odd Categories on IT, away from my Jazz / Rock primary collection that I otherwise enjoy Randomized on my #1 B2.
PRO TIPs
1) The Crossfade / Sequeway function is my favorite feature. I call it the "Fire the DJ" function. Btw, I run All ANDROID / Flac, utilizing Rooted Amazon Tablets (1TB) that act as Backups to the Brennans as well as multipoint User Stations. WD NAS, X-plore Android Dashboard.
2) YouTube Cache is also a way COOL Feature to explore/add relevant Content to your Collection.
WISHLIST:
1) B2 Software Window with a "Randomize" button allowing you to Mixup whatever you can Sort into that View. A Dynamic Playlist feature instead of just Static Playlists that require continual maintenance & updating.
2) FOLDER > SUBFOLDERS oriented Dynamic Playlists. I'm finding great value in storing/organizing Albums via folders/subfolders on my other devices including my 1TB Android Phone (sorry iPhoners).
3) Network Libraries Support via WebUI. - Span the Network for Music files. Not unlike what PLEX / KODI do.
I am Now Beginning to integrate Bluesound NODE for HiRes which also has an HDMI port to interface with B2.
Summary
B2 is a great Solo Nucleus for Modest 16bit/44.1khz CD Collections (250-2500), transforming and evolving as needed into a key building block component for monster collections (2500+).
Great Value for modest needs. Great Price/Performance Ratio. Raspberry PI Core has lots of capabilities, and commensurate Limitations (not a Cray).
