Hiking, Scrambling, Mountaineering, and Climbing

That's 2L, not 3, which I wouldn't recommend irrespective of its sale price unless its for a very specific reason i.e. I have an ultralight 2L waterproof that I use as a glorified wind jacket in the high Sierra in the summertime just in case. For actual waterproofs its gotta be 3L. @Aggi, I get that its a bit out of budget and out of budget is out of budget, but keep an eye out for a Torrentshell on sale or used regardless. Maybe its just in the U.S. but the decent colours go on sale quite regularly. Can be had for like $100. Could genuinely be the last waterproof you ever need to buy.
