I do use some line-skipping stuff, though certainly not at that cost. The main thing I have is a Nexus card, for frequent travelers between the US and Canada. It lets you use a special lane at land border crossings, and an automated kiosk for airport customs. Given how long land border crossing waits can be (hour+ is not uncommon) this is a very big time savings. The program cost $50 for 5 years (up to 10...the card lasts until your passport expiration) plus a half a day to visit for an interview. If you cross once or twice a year it's probably not worthwhile, but since I go up maybe 10-12 times a year, its a really big time savings.
Oh, and if you're flying domestically, you can use the TSA precheck lanes which are otherwise for elite frequent fliers.
