What's the final word on the TT bypass valve? Do they do just as good a job as Bailey or Forge?

Just replaced mine this week...the word is very good.
No need to $pend the x-tra money for the bailey or Forge.
It works very well....smooooooth!
I payed $26 for the TT valve.
I got a discount because i know 2 parts people.

The TT valve does a nice job holding more boost - but the design
is still prone to failure. The rubber diaphragm apparently tears or begins to fail in some cases. However... I believe the design of the Forge and Bailey's has also experienced some problems. Since they require adequate lubrication to allow the piston to open/close, some have stuck open.
The TT valve, at around $30 is a very cost effective solution - since you could theoretically go through 5 of them before spending the amount you'd spend on a Bailey. But then again, the Bailey's look sweet.
