I use this solder wick all the time and my local radio store doesn't have one. I build guitar amps with turret boards and use them to clean the turret when I remove and replace a component. Regardless, I've had the same reel for years and it was only 5 feet long (Soder-Wick 50-5-5). It's 25 feet long so I don't think I'll be needing more any time soon!
