OK I'm expanding my view. Would I need to keep looking, also I usually go to vendors direct not ebay. I do not have experience yet for what vendors to stick with, but was looking at these. I almost had a bodily accident when I looked at Riten first, but regained my composer with the other two . Thank you

Don't always rule out ebay & don't always trust Amazon. I have those 2 very same live centers, except the ZLC I have in MT2 & use with a MT3 sleeve..
That ZLiveCenter on Amazon $166.95 + $10.89 shipping. Buy directly from ZLiveCenter for $152.95 + $13.95 (shipping may vary)
I have that same Skoda MT3 live center purchased from Ajax as well but through ebay. Ajax's website, $174 + $11.89 shipping (shipping may vary). On ebay, Ajax has them "on sale" for $139 + $12 shipping. I've purchased a number of things from Ajax, even one of my Bison Set Tru chucks, Rocky is a good seller but his prices are usually cheaper on ebay.
FYI, if you purchase the Skoda live center from Ajax, you will not receive what's pictured. Pictured is the older model in black. You will receive the new updated version drop shipped directly from Sowa like pictured below. That is a good thing but if you purchase an older model elsewhere I would not be concerned as you probably wouldn't be able to tell a difference in use.
Don't rule MSC either if you have been a long outstanding customer or have a merged Enco account. Often my prices with MSC is cheaper than ebay or Amazon. The Skoda MT2 live center I got from MSC much cheaper than anywhere else I could find. IIRC the MT3 was cheaper at MSC as well but that was my fault for not checking before I purchased from Ajax.
You think Riten is expensive, check out Royal. Rohm also makes some nice live centers, still more than I would want to spend though.
