OMA or Jean Natais Lenco rebuild

You should also consider Chris Thornton of Artisan Fidelity. He does INCRDEIBLE work!

Do you have his table? Did you look at the OMA and Natais prior to making your decision?

After a lot of research mostly on the tables of these three companies, I discovered PTP audio. The tables are built by Peter Reinders of Peters Top Plate.
He uses Corian as a plinth, which some on Lenco Heaven say sounds better than wood or slate. Peter is a true gentleman and a delight to work with. At a price of 2500 euros it shames a lot of the other rebuilds. Wish I could give you feedback, but my table won't be here till next week. With the money you save, buy a Schick Tonearm or Pete Riggle Woody with a nice upgraded Denon DL-103. At least check out the 6moons review, or better yet talk to Peter. You will thank me.

2500 Euros = $3250. Does that include the starter turntable, or is that the price for work done to a unit that must be supplied by the buyer? If the latter, I am not sure the price difference between the PTP table and the other two options posed by the OP is that big a deal. However, I agree with you that Peter Reinders is a first rate guy who has done much to improve the performance of the Lenco L75. Scuttlebutt was that Corian is not so great as plinth material, but I would re-think that proposition, if Peter is using it. It must therefore have some merit. I use his PTP top plate in the context of a home-made slate plinth. In addition, I replaced the Lenco bearing with a "Jeremy" Superbearing, and I took measures to dampen the platter. The total result is most satisfying. I don't know what Jean is charging these days, but the OMA plinth, if you already have an L75 would seem to be on a par with the PTP, in terms of cost, or maybe even cheaper. It would then depend upon what else Peter is doing for his total price (and on what Corian sounds like as a plinth). I can only say that slate works very well with the Lenco idler.
