I agree, stick to a brand with local parts support.
Before you make your decision, start talking to the local fast guys, preferably someone who is sponsored and is regularly on the podium. Chances are this guy has a really good setup for your track and will give you a copy of his setup sheet...
Normally I would push TEKNO for someone without a sponsor deal, however we have no information given about the track surface. I would only recommend the EB410 for dirt/clay only... if the OP is racing on carpet/turf then TEKNO would be a mistake.
Another brand to consider if you want to save...
