Hey,
I use an Archos 4 in 1 CF adapter pn CAXX5N13N. It works great for just about everything except it won't work for the new xd format cards. Unfortunately it's the worst of both wworlds as it is only as wide as a CF1 device but has a HUGE MONGO plastic top that literally extends two inches beyond the CF Bay.
But it was inexpensive (off of ebay) at the time and no more often than I actually use it, it works just fine. For your purposes I would NOT recommend it on any basis unless you simply want iron clad compatibilty. It's also one of the few CF adapters that still accepts Smart Media cards.
Hope this helps,
