You also need a stepladder to get in a zx19U. The floor is mega high in them and the lack of A pillar means there isnt much to grab onto to haul yourself up.
In response to the OP, go have a look if you can at each of the 3 machines, or the dealer should be able to put you in touch with someone who has one if they don't have any stock at the moment. Get some prices and see who's keen to sell you one at a reasonable price. The Wacker is likely to be more expensive than the others but it will have more features as standard which may or may not be important to you. VDS for example.
Do keep us updated as you go, always good to hear what prices dealers are giving at the moment
Sorry for the massive delay with prices but here goes !
Wacker Neuson ET18 with 2 door cab, hydraulic hitch and VDS £24,700
Wacker Neuson ET20 as above £25,200 both plus vat
Looking at approx 3 month wait for new machines !
The dealer had an ET24 in that I had a look around , looked to be a well thought out machine, comfortable seat with good all round vision and very smooth to operate. It even has colour coordinated grease nipples for daily , weekly or monthly checks !
Just can't afford it at the moment, maybe next year !!
