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/

I SO would love to get a proper info here myself, as my beamer just not does a good job at upscaling a pixel pixture to HDMI.

The best solution i knew in germany was those converter that f.e. Ligawo sold. There were said to be ok. Yet i don't know if they properly do 50Hz. And they seem not to be sold anymore. Ligawo answered my request with the Info, that the converter chips just can't properly handle the lowres c64 image.

Upon my asking on facebook all boiled down to the expensive Framemeister. As either options not provide a proper FullHD image or are not available properly.

Have not heard about those KanexPro devices, so looking forward there myself.

I'd be also interested in this. Several years ago we tried at least 5-6 of the budget video/svideo to hdmi converters and all had some kind of frame tearing problem. Maybe the situation is better now.
What is also worth to consider, some of the converter boxes added considerable amount of lag (some added close to a second). For example to play games 'realtime' it is an important aspect as well.

Yeah, good point, latency also has to be taken into account. Some latency can be fine if your main purpose is watching demos and composing or pixeling, but for gaming you don't want more than a frame or two.

I have my CRT for when it really counts, so I can live with < 50 ms. Less is better, and if the OSSC had S-video input I'd buy it in a heartbeat.

My ideal would be some way to feed things into an eDP; that way I finally could build myself SX-128 out of my 128D :)

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...
