I bought all new, mostly gas powered stuff when i got my house 5 years ago.. no regrets on any of them. I think its worth spending a little more for more powerful equipment, makes everything easier.
Stihl BR700 backpack blower, thing is a beast, always starts in 1 or 2 pulls, cold or hot. My dad has the big REDMAX and they are pretty evenly matched.
Honda hrr216vka mower, changed the carb, spark plug & air filter this year, have changed the blades twice, i beat the **** out of this thing going over stumps, bushes, ivy, Belgium blocks, it keeps on going & mulches very good. Whatever you get make sure its self propelled, push mower *****.
Stihl MS261CM chainsaw with 20" bar, so far has cut everything like butter, if you dont have a lot of trees or live next to woods you could probably go with a non pro model instead. I rented a big Makita chainsaw from Home depot once and was very impressed with that too.
Ryobi cordless string trimmer 18v, works great for edging and light weed clearing. With the 4ah batteries i only charge it once every 2 or 3 weeks, yard is 100x150. For $50 on sale you really cant beat it.
I do have a Craftsman gas powered string trimmer that someone gave me for the heavy stuff.
Ariens 24" 250cc deluxe snowblower, goes through 30" deep drifts with ease, the auto power steering on mine was fine right out of the box.
The harbor freight 9" electric pole chainsaw is also a decent tool and cheap, just keep the chain sharp & store it over some cardboard cause the bar oil does leak a little.
