Only my opinions:
If you're mainly after image quality, or plan to record at low speeds, go JVC. The DR-M10 is outstanding and cheap but you may be plagued by the (in)famous "load error" that would hopefully be fixed by JVC servicing (it's a known issue).
If you are picky for audio CD playback quality, take it from me (I'm a musician and producer), the M10 is -as yet- the only DVD player that I know that may compare to an audiophile CD player.
If you're mainly after ease of use and reliability, go Panasonic. In your prices, the E55 I think. Softer and darker video transferts though. Not my favorite, but many happy users.
The Pioneer 220 is a good compromise, and has plenty of adjustable settings (maybe too much actually...).
Avoid LiteOn, not because image quality (that is outstanding), but because their software is rather buggy. This could improve in the future.
DVD recorders from other brands seem marginal to me. Don't take it for granted though.
