Alphatec
 

JB Hi Fi in Austarlia are selling a brand called Alphatec 50 for $44.00 which is an ok price.
Has anyone ever heard of them or tried them?, are they any good?.

Well I just took a try and bought a pack of fitty from JB for $44.00 and after making 35 coasters out of princo's I have now got 100% success rate so far with these Alphatec's. So I duno either there pretty good or I guess princo are just sh!t on some writers. :)
