HDMI upscaling on a budget

I love my CRT to death, but sometimes a more compact option is needed. Does anyone know of an HDMI upscaler that doesn't cost $400, outputs 50 Hz without artifacts or dropping frames, and shows aspect correct 4:3 with black bars on a 16:9 display? The $30 converters on eBay are crap. Specifically, has anyone tried these KanexPro converters? http://www.kanexpro.com/converters/composite/

Framemeister is the thing that does it? 50HZ and all that? No flaws?

I'd see if somebody who's into designing/manufacturing hardware could do a simpler solution. There's a lot of money in a cheap Framemeister clone.
The fact that there doesn't exist one yet, makes me think that it's actually not feasible...

thing is that it wont get much "simpler". and if you cant just take an off the shelf IC (which those $30 solutions do that work like crap) it wont get cheaper either :)

It gives by far the best picture I've seen from a C64 on a modern display, with smooth 50hz motion.

It can be *slightly* buggy on PAL sources. Once it's set up, you're fine, but every now and again I've found changing some of the options on a PAL source can lock up the unit.

I got one because I have a number of old consoles/computers that I wanted to hook up to my TV and I think it's been a good purchase. In particular, it handles 240P RGB extremely well.

One would think that affordable ADC+FPGA/CPLD circuits for this purpose might be around the corner...

Oh it's quite doable, and indeed the components are out there. It's above the level of most hobbyist engineers though (myself included), and commercially it's unlikely to be profitable, so... here we are.

LFT will rescue us, no worries. Right Linus? :D
