the Vetta framebuilding enterprise is run by Antonio Taverna and has a reputation of offering frames and bikes for price-sensitive customers. Some of them are very nice, others are quite disappointing, so you are basically taking a roll of the dice. Their website is: http://www.vetta.it/index_altra.htm

Because of the popular prices, there are many shops that have their "custom" shop frames built for their customers by Taverna and his team. I believe that I have once been in the shop Alberti shop in Ferrara but am not absolutely sure, so I can be rather sure that it was not a super interesting one (I always take note of the impressive shops that I have been to )

BTW, the headtube is so shallow that the stem is actually going noticeably uphill, this means that it must be about 68° or 69°. My guess is that the front wheel will have wheel flop when you turn it from right to left and left to right. It will be a great descending bike but perhaps not what you would want in tight confines.
