I love the Green & Yellow machine! Deere makes a good product, but their mower was only rated #14 & 27 in CU (May 2008). It's the #1 lawn tractor, though.
I bought a Troy Bilt (#22, 23, 26, 28) at Lowe's a while ago. It broke three times in three months, so I took it back and bought a Toro from my local Toro dealer. Love it, rated #2 by CU. There was another thread recently where Troy-Bilts were discussed a bit:

Having said that, if money is no object, Honda is consistently rated #1 in all reviews I've seen. For $700-$900, it ought to be...
As for the other tools, I've got a 13-year old Stihl string trimmer, which is OK (#1 in CU), and seems to be the choice of the lawn care crowd around here. They tell me nobody has a really good one that will trim without constantly breaking strings. Derre rates #2, and HD sells Echo (#3), which a lot of people seem to like. You might look for a power handle and trimmer/edger attachments if you'll only use them occasionally -- might save a few bucks.
I've got a real old hulk of a Craftsman edger which is a bear to use, but acts like it'll run forever. Haven't seen any reviews, but I like the Deere "Stick Edger".
