As to grinding a mirror, it's all whether you want to trade time for money. It's not hard to grind and polish your own mirror, especially if you have the help of the local optics guru at the local astronomy club.
The EP selection really isn't that good as a barlowed 30mm is an effective 15mm so you will end up with 2 ways to get to the 15mm focal length.
