You'll probably upgrade your gear over time, but the one thing that I would not recommend you skimp on is your backpack. You can find backpacks in the low-mid tier range that have similar specs to high end backpacks, but the materials, fit, and comfort are worlds apart. It's really hard to appreciate how much better they are until you've used cheap backpacks extensively, but I think it's revelatory the difference they make in carrying weight and preserving your body. It's the difference in having sore legs, but a functioning body over a slip disc and ****ed up back. Wouldn't matter much if you only ever carried up to 50#, but 60#+ and it makes all the difference. If all my gear burned up and I had to start over, I'd go budget with pretty much everything else, and buy the best pack of my choice (used). I can find $150 boots that are comfortable, but last a couple seasons less. Good glass is expensive regardless, so you'll probably upgrade it over time. Everything else, good enough is good enough. A good pack is worth every penny.
