Alternative to Nvidia spark?

I just spent the last two weeks trying to catch a microcenter in stock with a spark and then today the price went up 30% and now I can't realistically afford it. It was already pretty close to the edge of my budget, and now I don't think I can swing 7k for what I had been expecting to pay 5 for last week. Any suggestions for alternative approaches welcome. I really don't want to wait until 2028 to get started.
