I used to use a blade & lopper pole saw & I dreaded hanging new stands.  Several years ago I bought a Stihl.  Now I don't even blink about trimming any limbs anywhere.  Very happy with it.  Don't recall which model it is, but it telescopes, hangs over the tailgate of my 6'6" bed & was about $600.  The price hurt for a few months, but means nothing now.  It was a lot of money, but well worth it for speed, convenience, and years of trouble free use.  I can reach well over 20 feet up.  The first time you use it you'll wish you'd bought it years ago.
