I always buy corded apart from screwdriver and drills.
The only thing I have recently converted to cordless is the vacuum to a shark cordless because I had to.
Everything else is corded because it's usually £100 cheaper and 3 times as powerful.
Only buy cordless if it really must be.
To be fair the Dewalt is perfectly powerful and only cost £30 as there was a promotion for a free drill which I sold along with the 5ah battery.
Looking on eBay they sell for around £100 so should make a bit on it.
Mainly just trying to work out if the vacuum function in most is worthwhile.
