Yeah, any electric screen that isn't tab tensioned is likely to have ripples, or develop them over time. Cue weird shimmering effects in panning shots and some distortion. Screens are actually the harder buy imo - the pj is the easy part. Either way, if the screen is white and it's in an untreated room, you're going to absolutely crucify your black levels. Like cheap, decade old lcd grey black levels. Which takes you into the world of room treatment or awesome, yet uber expensive grey screens. For what it's worth - I budget around the same amount for a screen as I do for a new projector. A good screen will last you forever/multiple projectors.
Going back on topic. Have a look at https://www.avforums.com/ , http://www.hdtvtest.co.uk/ and http://uk.rtings.com/ , snips86x. Anything current, in budget and well reviewed on these sites will be a step up from what you have. Things have moved forward a good deal in the last 7 years. If gaming is a concern make sure you keep an eye on the input lag of the panel.
