I personally run a Hurricane to salvage when my friends and I run Missions/signitures.
If we are Hi-sec missioning and my friend runs a Golem then it's 8 highs with salvagers in.
If in 0.0 or low-sec or the Golem isn't being used, then I switch to 3 tractors and 4 Salvagers and a Prototype cloak to keep you safe should someone decide to crash your parade, or so you can keep invisible while your friend gets agro from the Rats.
We salvage everything, I reackon conservetively we probably make 30% total income again in terms of salvage which we wouldn't of gotten otherwise.
Reason for the Battlecruiser rather than a destroyer as recommended above (although there is absolutley nothing wrong with a comorant or thrasher as a salavager)
If you fit 2 Medium Cargo Optimiser rigs, and a full low rack of Expanded cargohold II's The hurricane gets over 2,000 m3 of cargo hold... which will easily be filled for large missions, but small ones is comfortable with one trip.
I would also fit one salvage tackle rig. A MWD (preferably a tech 2 however the YT-8 is good also)/if you are going into deadspace make it an Afterburner, A medium Cap booster when you don't have the luxury of the Golem, and you are going to have to run around to get to 20km of the wrecks, and a Small shield tank (probably best to go with 2 Large shield extender II's). I've also tried fitting Sensor Boosters to counteract the cloaking device, and even tried to dual propulsion the thing (sadly no joy on the last one) I feel the best trade off is the above, it gets the job done quick, and saves loosing the ISK.
However I do understand the argument that we are wasting our time salvaging everything, but I am of the old school opinion of look after the penny's and the pounds look after themselves. And at the end of the day with the Hurricane, even on an insane salvage mission like the collision of worlds, I am still only 5-10 mins later finishing then the runners themselves, although we have an agreement that they won't engage anything greater than 50KM away when possible for this to work.
