JG, towable lift to me is the way to go! unless you can afford a self propelled! yeah the buckets big! speed wise.....I have the control program for mine so it is probably close to the speed of a bucket truck.
You will make your money back times 10 if you utilize the towables multiple purposes, Ive used the crane attachment to set windows, trusses, etc.. gutter cleaning, flag pole repair/paint, church work, electrical, etc...
several of the twp`s in my area have me do odd work for them & they pay me good for such especially in slow periods, by the time they rent it, insure it, run it, return it! Its cheaper to hire me!
towables are easy to maintain & depending on your state very in expensive to haul down the road!
a $20-30,000 bucket truck is pretty much junk, its been abused and will need maintenance......costly maintenance, not to mention, road tax, registration, insurance, cdl, medical card, log books,inspection of truck & the boom inspection will cost ya!! new guy driving?...watch that driveshaft! LOL
there are pro`s n con`s, I have owned both & will never go back to a bucket, the future is geared toward "mini lifts" check out this months TCIA magazine. by the way boom inspection for my genie was $125.00 & is very thorough...taught me alot!
good luck, IMO you will profit more from a towable than a bucket truck...just the savings in fuel alone....beleive me!
Take care & be safe!
