How best to eliminate LP warps


I own about 2500 LPs, and I like to think they're flat.  Furthermore, I espoused the view that warped LPs ought to be discarded.  But lately I have found 2 or 3 of my LPs that do have warps but sound too good and are too precious for the music recorded on them to throw away.  So I am in the market for ideas on how to remove warps.  I am aware that there was a device on the market that looked like a large waffle maker, to be used for warp removal.  I think Furutech made it, but I never see it advertised these days.  I am also aware of the DIY method of placing an LP between two glass plates and heating the ensemble.  The question there would be how hot and for how long?  Any suggestions are welcome, especially opinions on the efficacy of the Furutech.  Thanks.  Please no comments on vacuum hold down; I think it's a great idea but none of my five turntables has that feature.

The Orb units work.  My local record store has one and they have flattened a number of records for me with it.  I've been thinking about getting one.

Here's where to get them in the US - Record Flattener – Mockingbird Distribution LLC

 

@drbond thanks for the info on Mockingbird.  I saw an Orb listed here on Audigon recently, but it was almost the price of a new one, so I passed.  It did get snatched up pretty quickly.

Agree with those that mentioned using an outer ring.  If your table will accommodate one, that's a great way to go.  I had one with my VPI Classic 2 and it worked great.  

I don't think it would be a good idea to put one on my Sota Sapphire with it's suspended chassis, which is why being able to flatten my records is appealing.  I have the Sota clamp which works well, but doesn't do much for warps where the outer edge is bent upwards.
