Well, this wasn't going to be an ad, but since I wrote to Mark anyhow, I thought I'd let you know my feelings about the MFFT as well. Here's what I wrote:
"Hi Mark -
I have an MFFT that I have used to compare with our Series IV 'Stiletto' focusers. Overall, the MFFT is a fine unit, but with a couple of significant downsides: 1) it attaches via threads to the t-adapter. Since thread turning is different on different adapters, the standard 55mm t-adapter length may not be exact. In short, the film-plane distance may be off significantly. 2) the target is well made, but difficult to use. Since the MFFT uses a grid pattern, it is difficult to tell when you are out of focus which way you need to refocus. 3) Since it is a straight unit, focusing at points near the zenith may break your neck.
My plainly biased opinion is that you would be better off with a Series IV in the long-run, especially if you ever have an inkling of getting into CCD someday.
That said, if you want the MFFT, the price is $90 ppd. You can order by credit card if you like. Just give me a buzz at 1-800-232-9416. Better yet, if you want a Series IV Standard Model, I'll give you $20 off the regular price.

Really folks, I have tried every focusing technique on earth over the past five years, and the Series IV is still the fastest, easiest, most convenient, and most precise way to focus a camera. Just about any 35mm, CCD, or Medium Format camera.
And since I am so convinced of this, I'll extend to you all the same offer I made to Mark. Order a Series IV 'Stiletto' this week (any model), and I'll knock $20 off of our regular price. In the end, all of us will be happier that you didn't wind up with another unused astro accessory in your junk drawer.
