The Vibe series 1200d and 1800d do rated power. The opti line is thier best no doubt but for under 200 new they can't be beat. The rest of Lanzar is trash.
I have had every line of Autotek from Mean machine to the one I have now in the Steet machine and all have done awesome. For budget, the SM1-1000 IMO is hard to beat.
