I love the Douglas firs that surround our new house, and after spending a few weekends cleaning gutters, I decided it was time to fix the problem. I interviewed MasterShield as well as the other guys and got competitive estimates from both (although the MasterShield's number was actually a little lower). I also saw samples from both, got explanations on how they work, and learned firsthand why the gutter shields I bought at Lowe's (as a test) just plain don't work. Jim was very patient and knowledgeable in explaining the options, and even identified some flashing issues which needed fixing, as well.
After a horrendously wet winter, I don't miss the clogged gutters one bit. I was a little surprised at project completion to receive a telescoping brush to clean my self-cleaning gutters - and it's proven useful for the 3 or 4 times I've needed to remove needles which tend to collect below the valleys in two locations. So it appears that I need to budget about 30 minutes a year to attend to a couple of trouble spots. I'll take it!
I highly recommend MasterShield, for the product, the workmanship, and the service. When you decide to give up the gutter-cleaning ritual, you'll probably receive an estimate that's more than double your budget. (especially if you decide to replace rather than just cover your existing gutters. They'll explain why the system works much better if the gutters are located to allow the covers to maintain or exceed the roof pitch.) You can probably negotiate it a bit, but then do it anyway. You won't regret it.
