Part of the holiday celebration is getting together with the family and decorating it. If you treat it like a chore, (oh woe is me, I have to string the lights on the tree), then why bother with a tree, artificial or real, in the first place?
Around here: real tree = $0 to $20. Hell, I think they're under $20 at wallyworld. Artificial tree that doesn't look like a tacky piece of plastic crap = $100. Usually, after 5 years, those prelit trees start getting to be a hassle with lights burning out. Real tree - once the bulbs start burning out left and right, you just throw out the whole string and get a new string right after Christmas for $2 on sale.
Needles in the carpeting? Depending on the type of carpet, it can be a pita. Depending on how long you have the tree in the house, the humidity in the house, how good you are about keeping the water filled in the tree stand so it doesn't dry out, etc., you can sometimes go a few weeks without any serious dropping of needles. Of course, you can buy the tree at wallyworld, hope that it wasn't cut down in Guatemala 2 months prior, and discover that by New Years, there isn't a needle left on the tree. Personally, and particularly with younger kids, I would never go a Christmas without going out and cutting down our own tree.
And, why the hell are people having trouble with sap? Seriously?? I've never heard of that problem before, except perhaps sap on the hands of the person trimming the bottom of the trunk just before sticking it in the tree stand.
