I probably paid about $700 for my 75g planted in total. Look on Craigslist for a tank. Leak test it and much cheaper than a new one. I'm also about to build a DIY stand for my 40 breeder. Much cheaper and sturdier than store bought.
Oscars are also very messy I wouldn't go below a 75g for one. That's just me though.
Hope all goes well and welcome
