Had a great time hunting this year, saw lots of doe but no bucks

Anyway, I was browsing through the regs and saw archery has any deer for a good portion of western Washington. I was looking into it and thought about getting a treestand. I wanted a treestand anyway for coyote when calling because I don't want a kitty/bear to surprise me, especially with a bow.
I am aiming for an economy priced climbing stand, since most trees (in the thick part of woods) are tall with few branches at low levels. They absolutely have to be tma certified, I also want to be as safe as possible.
I found this one:
http://www.amazon.com/Ameristep-9500-Grizzly-Climber/dp/B000BSWE6E/ref=cm_cr_pr_product_topWhich is an good price. A review said the harness was poor though, another said its comparable to the 250 viper.
It is 30 lbs though, but I think I can access pretty much any part of the woods by a 2 hour walk or less, but 30 lbs plus other gear might make it rough.
Then there this one:
http://www.amazon.com/Summit-Treestands-Viper-Climbing-Treestand/dp/B004V98T2W/ref=cm_cmu_pg__headerHave read a lot of good things about summit and its 10lbs lighter, but is it worth the extra $130?
