Hi there and welcome to the forums.
Lately we didn't really have many new members, so not really many active topics here, but feel free to revive any that interest you.
I'd recommend you a palmtop, but i guess it kinda depends a bit what you wanna do with them and where your focus is.
The HP Palmtops - namely the 100LX and 200LX are usually always available on ebay. Their pros are: Light, small, good battery life, good software, pretty compatible with most PCMCIA/CF combinations and cards. Cons: Terrible keyboard, no parallel port, just 1 PCMCIA port, serial port needs obscure proprietary adaptor, plastic hinges tend to break easily.
Still if you can live with that then the HP palmtops are pretty good.
If you're looking for something special then let me know, i have loads of spares and sometimes already thought like "Hmmm, maybe i don't need 3 of this model"...
