What's a Fair Price for Toku Toys?

I'm looking to sell some stuff on Ebay, but I have NO clue how to do that or how people get such good looking profiles for their items up.

How much is a henshin belt worth after it's been "modded", i.e. cutting out that stud at the end so you can loop a strap through it?

Does it cut it down to half the price or more?

And is anyone good at that HTML voodoo that people do on their items?

It all depends. I mean a Dragon Buckler could be $500, while a MagiPhone for $40.

I'm gonna try and sell me Garren Buckle DX... was gonna throw in a Garren action figure to boot.
