While it looks good as a cover, I wonder about the idea of doing a print run. It can't be cheap to do a run of 60 page books considering that the G:T planet surveys were 32 pages and cost $7 USD. I really don't think that this would be worth $14 to a prospective player. (Checks cover pdf) Ok, make that $12.
The rules are extreamly limited by what you are able to play as I've mentioned elsewhere on this board. In essence this is like a copy of the 3rd edition PHB that only lets you play clerics. While there are some for whom that won't be a problem, it will be for quite a few others. I really can't see these doing anything but gather dust on either a store shelf or a collectors bookshelf - and niether end gets you any new players. For it to have any value to the T20 line, IMHO and all that, it needs to be either free or have an essentially nominal price. Even a huge print run selling out wouldn't allow for that.
You're already giving the impression of being an extreamly expensive line. Yes, I understand your POV, but the sticker shock is going to be real and intense. Charging for this will only make this impression worse.
I really think you should keep this electronic only. If you must print some, use them as give aways at Cons and charge back the costs to advertising. In that case, do leave the price on the cover as it helps people believe their getting that much more - much as many catalogs have a price that is almost never actually charged for them.
As always, YMWV.
