Need some insight on lab glass. Seeing a wide range of prices. Borosilicate, heavy duty, brand names, et al. Don't want to over invest, yet I don't want problems either. Any advice?

Borosilicate is sensitive to some acids and alkali, Soda Lime glass is basically Pyrex and is questionable for lab use. NaOH at higher temps wouldn't be viable in plastic? I have access to a scrap dumpster of a company that is loaded with SS tanks, tubs, tubing, et al. They typically handled HCL. Is the heavy duty glass worth the investment? I'm ADHD and self educated, so I'm not sure exactly where this journey will lead. I do appreciate all input and advice!
There is a reason "ALL" lab glass is Borosilicate.Borosilicate is sensitive to some acids and alkali, Soda Lime glass is basically Pyrex and is questionable for lab use.

I have no accessory tools either, this is a complete start up...I have several of each size from 50ml to 4000ml. My most used are 50ml, 100ml, mainly for measuring small volumes. The most broken 2000ml and 3000ml and the most used. I usually buy 1000ml by half dozen box’s as they are used for most everything.
I like 2000ml vacuum flask but I have one 1000ml flask made of Nalgene polypropylene plastic that can with stand a vacuum stronger than my AC vacuum compressor can generate. More than enough to vacuum boil a solution.
When I first started I used 100ml, 1000ml and 600ml. The 1000ml was the most used at the time.
It is prudent to note that mostly in Europe the heat resistant household glassware that is marked "PYREX" is fairly standard borosilicate lab glass.If I recall correctly, boro glassware is resistant to a bit over 425 deg F. Pyrex is formulated to have a low thermal expansion coefficient but it can break if too harshly treated.
