Yep, look for a Joytech e-mode.
Its exactly the same device, they are made by Joytech and rebranded for TW so you almost certainly pick up an e-mode for less than TW want for their version.
PBusardo on Tasteyourjuice.com has done a really in depth review on the e-mode which is well worth a look too.
Actually, scratch that I was thinking of a different TW model but the same general advice applies, most TW stuff is rebranded gear from other manufacturers and is usually available elsewhere for less money without the "devil" branding.
Nothing wrong with TW stuff at all, it's what I started out with but you can often get better value elsewhere...
