Yes we phased out the standard B5 & B6 engines a little while ago as the amount of different engine versions that we making was getting too large. Also in general engine pricing of our competition has been increased quite dramatically the last few years and we decided that with our Pro-II model we offer the best performance and feature set in comparison to what others are offering at a very atractive price point! To give you an idea of how our engine compares to the competition here is some pricing from A-main's site:


Werks B5-Pro II $284.99

FX K501 $379.99

OS B2103 $479.99

ProTek Samurai R03 $399.99

Tekno Bloc 2 lbm $469.99

Reds 721s $359.99


So as you can see we come in very agressive price wise when compared to the other engines currently on the market with similar feature sets!
