@petermillard has a youtube channel. He reviewed some lower priced models, well within your budget. I'll post the link if I can find it.
Thanks. All my tracksaw-related videos are in a playlist here -
TW P1; What's a tracksaw & why use one? [video #277]
If the OP is new to tracksaws generally, it’s probably worth taking a look at the tracksaw workshop series as it takes you through the whole process from unboxing to getting up & cutting.
I own a lot of tracksaws and I’ve used most of the ones that are available here in Britain; they will all cut a straight line, they will all break down sheets for further machining. In my experience, there’s very little to choose between entry-level plunge saws - they’re broadly two basic designs and they’ll all do the job. My only word of warning would be the Aldi/Scheppach saws, where they’ve made some odd decisions re the basic design that makes the saws harder to use with alternative rails.
Pay a little more and you may get a few more features but e.g. other than the colour scheme and soft start, my ~£170 Triton appears identical to my £99 MacAllister, which is a dead ringer for my 4 year old £80 Titan. Actually, I’d say the Titan has better castings… Move further up the price range into Makita / DeWalt territory and you get better quality generally, better dust collection, a better ‘experience’ and a tool that can be used all day long for paying work.
You’ll want longer rails for breaking down full sheets and the best value are currently the Excel 1.5m at £35 - they’re the closest copy of the Makita rails I’ve ever found, and most saws fit on them; they have an additional anti-tipping lip that gets in the way of some saws and accessories, but it’s easy enough to remove, if necessary.
Best value upgrade to any entry-level saw is a better blade, and £20 spent here can transform the quality of cut.

edited to add; my experience is largely with corded saws, not cordless.
