i just moved from san diego to portland with 18 boxes of records, and two systems, i decided to move them myself while the moving company did the rest of the stuff. pack tightly in new or newer boxes, and do it yourself as movers may want to cram them all in there with no care. check the gross weight of the truck you'll be driving as the boxes add up quick. i think i may have gone over my trucks limit as i was pulling uphill at 40mph, oops. i think it's a little more expensive to rent a truck solely for records and stereo stuff, but ultimately better as no one will handle it as gently as yourself. oh and if you distribute weight evenly over a floor full of records your ride will be alot nicer, this is what i did, and nothing was damaged on my two day trip. hope this helps a little,
cheers
