I've been considering the same. I always wait a bit after first release of anything to let the bugs get worked out and let the prices settle as well, but this time I'll be waiting a bit longer.
Today my budget got eaten by a hotbox. My Jeep's left brake caliper got stuck, started smoking, then caught fire when I pulled into my driveway. A quick splash with some water and a dowsing with the hose put it out.
To preserve your Trainz budget, consider doing the work yourself John. Was quoted $275 by my very honest mechanic for a complete rear brake overhaul.(cylinders and pads) With parts from Rock Auto and my own labor I came in at less than $25.
