IMO you're better off with a DOM. Then you only need the XTIDE card. No CF adapter is necessary. Besides, DOMs are waaaaaaaaaaaaaaaaaaaaaaay less fickle than CF cards.
I've been using a 2GB DOM for a couple of years in my tweener without any issues whatsoever. The guy I got it from on eBay is still selling this DOM and it's even cheaper now -- under $15.I agree that a DOM has certain advantages over a CF card, but they aren't as easy to access. In my PCjr. I have had nothing but trouble with a PQI DOM. My CF card had no issues and they are easier to find new.
I've seen your price estimates for boards, kits, etc., but you didn't mention what you might be looking to get for the fully assembled units. Care to take a stab at this? I can't put one together.The boards should be $10-15 for a bare board, I'm going to sell parts kits and fully assembled/tested units as well.
I have had very good luck with cf to ide adapters from eBay its always the cards that let me down
It's got to be in a specific mode to work as a non removable drive and good luck

Yep I use DOMs with both of my XT-IDE setups due to weird data corruption issues with IDE->CF adaptors.
If you're talking about the original XTIDE board, there are two potential issues - first, that CompactFlash is a CMOS specification and therefore transceivers need to be HCT type, and secondly the timing in the 16-to-8 MUX in that design is not to specification. Furthermore CF-to-IDE adapters sometimes implement card power supply very badly.
Keep in mind that the CF card was not designed as a replacement for a vintage hard drive. So the fact that they sometimes work in that application is just our good luck.
Of course DoM (that supports ATA-2) is a very convenient solution if data exchange is less of a requirement, but I don't concur with the above since CompactFlash IDE mode is a full T13 compliant implementation, albeit with CMOS levels as mentioned. Conversely DoM are typically TTL (eg this) and sometimes implement SMART.
As mentioned already, many of the IDE-to-CF adapters are the source of compatibility issues (perhaps 90%), the remainder being occasionally we come across CF cards that don't correctly implement 8-bit mode. The issue with the adapters is that the 5V power is delivered through a diode, actually at about 4.3V - which is totally out of spec for either 3V3 or 5V operation. Cards from all the common brands - SanDisk, Transcend, Hitachi, PQI and Kingston to name just a few - have been pattern tested for hundreds of hours on these adapters.
