Penta Premium stringers have a good rep AFAIK, PP's not so much. I bought my second stringing machine a few weeks ago, and went with Gamma again. A Pro's Pro with similar features was half the price, but I just don't trust the brand enough to take the plunge.
I would either go with the Penta, or buy a Gamma, Alpha or Prince and add the Wise later if needed. In Sweden you also have Tyger AFAIK, also worth a look IMO.
