Maybe he wants something new and doesn't want to shell out for the TS9 or TS808.
Also, a lot of people badmouth the reissues and would rather buy something that they think is based on older Maxon-produced pedals that are reportedly better.
Finally, some people just seem to hate Ibanez no matter what and would rather buy a knockoff than something that had the name on it.
I don't know; personally I'd get a TS7 if money were tight, a TS9 if it weren't, and a TS-808 if I wanted a real smoothie and had the jack for it.
