I also would add that if you can find the TST's in stock and for a good price, to not mess around with those. If you find good deals with this hardware, better to jump on it as it can be very hard to find again when you think you're ready in 6-12 months time. Prices have been going up for the past few years as well. Just think about where you want to head for tactile and perhaps maybe find a way to pull the trigger all in one go.
