DR Highbeams for me. I paid about £20 for my last set from the states, so wouldn't consider them particularly expensive.
I've also been very pleased with their longevity. I gigged my G&L last night and thought the sound was spot on, growly and punchy. I put that set on last Aug/Sep, So, about a year and I think I've used that bass for about 15 or so of our gigs, some of which have been extremely hot and sweaty.
I do always clean the strings down after each and every gig and give them a wipe over with Fast Fret.
No plans to change at the moment, one less thing to worry about
