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.

As @petg60 and @drbond just said, The Vinyl Flat Record Flattener, $159.95 direct from Vinyl Flat. Accessory heating bag The Groovy Pouch $89.95. Both @slaw and I (and Mike Fremer, etc.) have found it to work very well.

Mild/"slow" warps can sometimes be eliminated by the use of a good reflex clamp, standard on the old VPI’s (1/4-20 threading). It’s best if the top of the spindle is threaded, and of course the clamp itself. BDR made a couple of great ones, one a 1-pc. the other a 2-pc. I believe there is a 2-pc. on USAM right now, priced at $150.
