There used to be a pretty good business that did tent pole replacement for a variety of models but they went under.
I'd suggest just going into REI and getting some shock cord and doing it yourself.
Even if there is another business out there that can do new poles, 13 year old tent is pretty old. At least the metal/carbon tubes aren't bent outta whack.
Not sure how often you go backpacking but I picked up this tent from Amazon a few years back and it's been great. Way cheaper and about the same quality of my Marmot 2 person backpacking tent. Only difference is weight... but if you're not going out into the bush too often or for extremely lengthy periods of time it's worth the $ savings.
It's the yellow one you see in some of the pictures.
j/k it's an ALPS Mountaineering, probably one of the Zephyr models. They are nice and light and the thing I like is they have two doors and vestibules, one on each side.
Maybe take a look at one of these, I have used this brand before in the snow (A slightly different 2 person tent) and as long as you plan for snow you are good to go.
Since I'm new at this (I have however been camping in wilderness multiple times for 3-5 days, just never backpacking) I've been reading a ton of guides. I don't have a huge budget since this is something I'm just getting into, but looking around at different reviews this seems to be the best stuff I can get within my price range. If anyone cares to take a look and possibly give any suggestions I would appreciate it.
Tent - I wanted a two person because the weight difference between this and similar-priced one person tents didn't seem large enough, and more importantly I plan on backpacking with SO or my sister, so the split weight from only having one person carrying a tent seems better.
Backpack - Once again, budget, but seems to be exactly what I need.
Sleeping Bag - I'm in Louisiana, so nearby backpacking spots such as Texas don't warrant me buying a super low F rated sleeping bag. I don't want to be burning up and I figure once I get to the point where I'm hiking in colder weather I won't mind dropping more cash on a better rated sleeping bag.
