Where to buy a new cylinder?

I have a tapered 2” diameter cylinder and would like to purchase a 2” straight cylinder, any recommendations?

Thanks

Last I checked, LeLuv offered good quality cylinder with a flanged base rim for about $30. LAPump Distributors offered one with a wider (for comfort) base rim for about $89. And PumpToys offered a VelSeal cylinder with a thick silicone gasket on the base rim (for even more comfort) for $115.

Thank you!

Both ebay and amazon sell them. Inexpensive enough to use 3 different diameters and lengths gradually over time and it worked.
