People designing things will buy a CAD package which can cost anywhere from $1,000 up to $50,000. Complex solvers like antenna simulation or computational fluid dynamics can command big prices. FPGA design software. Simulators.
The are lots of things $1,000 should get you when you pay that for software. It should get you a phone number that someone will answer during working hours. A support ticking system where a bug report will always be resolved to either a fix or a workaround.
Think of it this way, if you buy a piece of software that costs $1,000 and using it you can do work for a company that generates $100,000 in revenue? Then that is a not a bad investment.
