You may have to disconnect the brake and tweak the spokes with a spoke wrench in order to ride back, but that's a relatively small price to pay to keep from walking back. You mention wanting a solid rim. Instead of going that route, it will probably prove less costly and more effective overall to go with a rim that has 36 spokes, as opposed to the more traditional 32 or 28. The more spokes you have, the more strength the wheel has. Also, if you can get thicker spokes, the wheel will be stronger.
Spokes come in different sizes and used to be classified in a confusing manner.
Keep your arms and knees flexed so that they act as shock absorbers, allowing the bike to move underneath you in a fluid motion, instead of bringing all those grams down on the rims in sledgehammer fashion. As far as making your dollar go further, what I suggest is that you check with some local shops to see if they have any special deals on special wheels that for one reason or another have wound up being sold as generic wheels. These special wheels are built by reputable companies but just got mismatched somehow, or there are more wheels than there were bikes needing them. Many companies cut their losses by reducing inventory. The result is you get a great wheel for a wonderful price.
