Hertel Super Hot Sauce is cheap and will be fine for most of your midwest conditions (except creaky cold snow and warm wet snow), unless you begin racing seriously. You can order here: http://www.hertelskiwax.com/Hertel_H..._Wax_s/127.htm
We buy the St Louis Brick. Some of us are just beginning to experiment with Alpinord's waxes, so check the Maplus Wax Test thread regularly to see how it's going.
If you like the way your skis are handling, you can keep the 2deg side bevel. Just make sure you're maintaining them regularly. If you find that you're slipping around a lot on the man-made and icy hard pack, you may want to consider a 3deg bevel. Many of us eastern and midwest skiers just re-tune to a 3deg as soon as we get a ski - but we've been doing it long enough to know how it can/may change the handling characteristics of the ski.
