Who uses one of these?

Which ones are the best? Is it much cheaper to DIY?

Gardiners backpacks are great and most, myself included strap to a trolley.   The pack back cost me around £107 Inc vat n delivery to Doncaster.  Then it's whatever price to pay for a trolley and most I've seen buy a cheap sack trolley which end up being too flimsy.
A good sack trolley is the handy sack trolley (I think it's called, can't remember now) for around £60 - £70 but these are sturdy with pneumatic tyres which I feel are a must.
If making a trolley, the parts are relatively inexpensive and you can tailor it to your needs and they are relatively easy to make.

( don't have to watch it, but this is my you tube vid I did about it and in the description I listed the parts)

I remember you making your trolley and I love to tinker, but I'm busy at the minute and unless its a big price difference I would rather just buy one.

DIY is great, when it goes well! Time consuming and frustrating when it doesn't!

I made mine in one evening, Admittedly when everyone else was in bed mind you, but it was just in one evening.   I think the price including the trolley came to around the same price as having the back pack delivered (which you then need a trolley for)

However like you said, the back pack is all self contained and looks the part already and compact.  I would hate to use either full day as its a pain walking back to the van to fill up but for those odd times you need them, they are great

My Gardiners backpack is still going strong after:

1. using it for awkward access to clean windows (got fed up with that and if the hose don't reach, I don't clean it)
2. Using hypo to clean walls, patios etc (and not cleaning it out properly)
3. I currently use it for FSG cleans and I put No Nonsense Degreaser in it. That I like.

I may get another one for hypo and even clean it out properly after each use.

You will probably find most backpacks are just adapted sprayers with different stickers on.

They are all essentially the same, moulded plastic with simple internals, a cheap Chinese pump and a small battery.

Do you actually need a trolley. Personally I don't take on work that I cant get parked outside or close.

I have a 16l backpack with a handle.

I prefer just to pick it up and walk round the back with it rather than faff with a trolley. Only used on the odd terraced house really.

i only use my gardiner backpack for chemical application these days(really dirty conny roofs and f/s/g jobs)with virosol.....

my 18 year old daughter works for me full time.
we both use back packs ....we fill them with a transfer pump from the tank in seconds...
we don't faff with a trolley.  she is a about 8 stone and just carries it now without thinking about it. hers is 16 ltres.
mine is 20 litres.
mine is like triggers broom. its had several pumps and several batteries....and I always have spares so I can change on the move .
they are simple tools but effective when there is 2 of you.
I worked from a reel for 10 years before this way. I find this better for 2 people
