Bought a TBM planetary type II 9mm for $49 plus postage from Sylvian and very happy with it. Excellent value for money. Feedbacks are all good. A reported comparision was it is neck and neck with the Televue Radian. Just check out the Classified Eyepieces section and I think it is still for sale.
I would upgrade your 4" to at least a 8" Dob if I were you.
Cheers
