Need Tuning Box Advice

Specifically, reviews, impressions of specific brands. I am looking for a tuning box for a 2000 Golf TDI.

I realize chip + injectors is a better solution, but I want to stay in my regional scca street tire class for the rest of the year (injectors would bump me to street prepared, maybe next year if the rule change to allow boost changes in street prepared goes through).

So basically I'm looking for one that I can use for a few months that will work well, not be crazy expensive, and I'll be able to resell on ebay or here when I decide to make that big jump in class.

I've got a Van AAken for sale. Only used for 6 months. Works perfectly and will fit your car. Plese email pthunell@hotmail.com if interested and put "TUNING BOX" in subject line.
