We frequently refer to your requirement as a "bit bucket". All the processing is done upstream, you just need something to catch the bits. Below are some models all under $1k.
These are models with a good reputation for reliability. If you are buying new, 661 is probably the one to go with. The others are fine if you can get a good deal on a used one, but I probably wouldn't buy one new.
- Marantz PMD661 (newer, compact), takes SD cards.
- Marantz PMD671 (larger model, a few years old), takes CF cards
- Tascam HD-P2, takes CF cards
The Edirol R44 will do 4 tracks, and the Tascam 680 will do 8. You may not care about that now, but many people like the ability to do AUD + SBD mixes at home afterward, and you would be ready if you want to do that later.
There are some M-Audio Multitrack and MT2 models. Attractively priced, but some people have had reliability issues, I'll leave it at that.
2 hours of 24/96 won't quite fit on a 4gb card. You need an 8gb card, and those are readily available.
