I use the Orion Tele Track GoTo mount for my PST. It works well, can carry an additional small white-light solar scope side-by-side with the PST if needed, and can also be used for night-time use on the stars. While the sun isn't in it's alignment star database, I easily get around that by noting which star the sun is close to on my planetarium program, then aligning on the sun as that star, and my best estimate on where I think Polaris is. This works so well that tracking is always dead-on for periods of up to half an hour before needed to be tweaked, at the low powers the PST is used for. And at night, when you can align on the stars themselves precisely, tracking is perfect. It functions on either internal batteries or 12VDC. It also has a 12VDC output jack. A table-top mount is available as an accessory but it comes with a full-height tripod that works well, from my experience. Right now, Orion has a Tele Track on-sale in their Clearance Center (typically customer returns or cosmetic "seconds", guaranteed to be fully functional, at sometimes impressive discout). $50.99 off the regular price: http://www.telescope.com/control/clearance-center/accessories-on-sale/refurb...
