I have several OS GT33's. I have no plans to get a DA35 IF it ever comes out...

The 33 has all the output you could possibly want out of 30cc-40cc class engine. I have tested several others in the 30cc class and nothing will touch it......Tower's super saver buys the engine for 350 in most cases so pricewise, it's hard to beat too. Tthe early engine I purchased was purchased at the full Tower price and to me, it's still a bargain; it's been that good for me. As always, YMMV.............
