I have been following this thread for a while as well. 4250 does seem high when you hear it.... Let me say this first I am not rich at all however 5 speed conversions do not come cheap I was continuously messing up 727s and running 3500 RPMs going down the highway I bite the bullet and converted to tko 600 from Keisler! While it's a nice unit the pricing is let's just say more then you expect! If I would have had the option to go with this unit from Jamie for around the same price with less install work and hassle this would be the choice I would have made! No offense to shafi or gene great guys gene has helped me on the phone many times. However I like many others wish the price was cheaper but it's not far off of the rest of the group!
