Does anyone know a site with comparisons between different powerboxes?

currently i'm looking at the powersystems box(http://www.powersystem.fr) or if it's worth the extra price the unichip(fully programmable piggyback computer) from dastek(http://www.dastek.co.za/)

These are the boxes my tuner uses.

anyone uses one of these?

ps.: i don't wanna go into a discussion about boxes vs chips as i want to disconnect it when i want(warranty stuff) and i'm living in belgium so no jabba tuning for me(too far):-(.

greetings,

A happy(new) owner of an (for the moment) 110 bhp tdi octavia elegance seeking for that little extra(power).

If you want a box, there is a company in Belgium called tuning box

they are based about 10 miles from Spa ace track
