First Galleto (clone) I bought,6 years ago,cost me 600 quid ...now these are much cheaper ,around 25 quid!
That seller should be fine and they are cheap.I get a lot of my customers to get these off ebay as well and I been using the next seller for 3 years now and his stuff always reliable and about same price. EOBD 1260 ECU Flasher Galletto Tuning Map Tool OBD2 on eBay (end time 07-Feb-11 09:55:02 GMT)

Just buy it for it is is!Read and Write ECU files(maps)....make sure you dont use the "so called" mod files on the cds that come with it , or your car will never start again
As a bonus,maybe in future you can read and write a map on a friends car and make some extra cash .....I dont mind making and selling your mod files
