The tivax stb-t9 digital TV converter box is one of the best converter boxes that is currently available for sale.  It can be purchased for around $55 and the price can be reduce to around $20 if you use one of the government $40 off coupons. I recently did a review of this converter box and found that it was one of the best ones because of its superior picture quality.  When I compared it to several other converter boxes I found that nothing really compared to it in regards to picture quality.  It also comes with very high quality sound and a lot of good features.  Some of its features include a universal controller and an excellent electronic programming guide.
