Thank you for the suggestion but I've tried to limit the cost to $150. With the TranzX I'll need to buy the cable and lever. Also, my seat post tube is 34.9mm I'll need to by a adapter sleeve. Apparently that's not a common size. I found the DNM dropper that has received good video reviews:

Again, thanks for the response.
UPDATE: I'm following up on your suggestion and looking at reviews. I see that this dropper does come with the necessary hardware. Soooo.... more research is in order.
