**** $1000 budget on a skimmer for a 70 gallon tank? Most people don't have that kinda budget for their whole system! lol Well your choices are pretty limitless. One thing if you go into the boutique high end skimmers, go for actual ratings and don't oversize it like most of us do with the more budget oriented brands. That's where problems usually happen with tuning and getting proper skimmate. Any skimmer with a good sized pump, good air draw, and a 5-6" body would do the job very well.
