I prefer the wedge type and got mine from tools4cheap. I was extremely happy with the QCTP and Jeff's service.

I also prefer the wedge type. I started with a Phase II piston type and didn't care for the feel when tightening the tool holder down so I sold that and bought the wedge type. Much better feel to it. That being said, I have a friend who did just the opposite. Bought the wedge style, didn't like the feel, so he bought the piston style and is one happy camper.
My very first QCTP was for my HF 9x20 lathe. It was a Harbor Freight QCTP and the fit and finish were equivalent to a Phase II at the time. It worked very well for me. I'm not sure if the quality of the HF QCTP has changed since it's been years since I had the 9x20 lathe.

By "a worth owning" do you mean one that is not the bottom of the barrel in quality yet not top of the line either? If so, I would suggest a Phase II piston style. The quality and cost are reasonable, although they have really gone up in price so if those are too expensive then the only other one I can recommend is the one from Jeff at Tools4Cheap.

$90 for the AXA size and $110 for the BXA size.

I've heard nothing but good things about Jeff and I've bought a few things from him and have been very happy with the quality and price.

Hi
I bought one a while ago
It is a piston type
To get the habdle to "park" where i wanted it i put shims behind the pistons
It takes very little to make a big differance

As you can see i made a new lock nut up for it as well (one less spanner to find)
I also modified some large tool holders to fit directly on to the tool post
They were warmed up then allowed to cool very slowly
They were tough to machine but machinable
I can now use all the big tips i have
The parting tool is very rigid

Large tool holders can be bought fairly cheaply on ebay
Tha facing tool shown was donated by Rob Wilson along with some tips

I like the price but what does he mean by machine to fit?

John,

That's a good idea to mill the large insert tool holders to fit right on the tool post. Smiley-signs107
The tool holders didn't warp when you heated them?

Jerry,

He's talking about the T-nut that fits into the compound. All (most?) QCTP come with a blank piece of steel that you have to machine to fit your compound.

Hi
Ed
No they were ok
I did have to clean the threads up
All i did was take the temper out of them
The tool holders were useless to me without doing this
I tried a large tool holder for them but i had issues with centre height & rigidity
All they cost was a dove tail cutter and some gas Big GrinBig GrinBig Grin

John,

That is a clever idea to use large insert holders.

(With regard the heating you just like to set fire to things Big GrinBig GrinBig Grin)

That parting off tool looks good.

John,

I agree. Parting scares the bajeebas(?) out of me. I like your version of parting tool. I may have to watch ebay for a large insert parting tool to modify like you did.
