That Alpha does not seem very expensive, 200eur here it seems.
We had a guy last time with DM1 running us with an equally priced Alpha, but orange head, a .21.
It was awfully sluggish (sorry to say), had no match to us, like IGT2 with Orion US Spec .21 or others. That guy is looking into RG cars now..
But we figured that if he stays with the DM1 it would need a .28 or similar to be competitive.
