Z-wave CH + HW programmer suggestions?

Here in the UK most zwave devices seem to be limited. Just wondering if anyone can suggest a good programmer for use with HA.

I’m looking at the Honeywell YTH8320ZW1007 but it can’t be bought easily in the UK, and it probably isn’t even supported if it needs to be imported

I’ve not used any of them, but Vesternet has a range of such devices.

actually they only have 2 zwave devices!
