I do NOT take in any extra tools for repair. I am a tool repair technician based in co Donegal in Ireland. I repair all brands and types of power tools new and old for a living. For me, professional power tools should be reliable, repairable and should last year's. Working with all tools...
We have a Husqvarna that is still going strong after a lot of abuse, so I would probably go for another myself. Wireless has made a lot of progress so I would definitely be tempted to swap to it.
Kress are also getting a very good name, worth a look I’d say.
Husqvarna spares are pretty widely available, if not the cheapest! I've recently replaced the battery on mine.
I'd still be concerned about wireless unless you have good physical boundaries to limit where they operate. Domestic grade GPS just isn't all that accurate. I've the 415X which uses a boundary wire, but has GPS in order to allow you specify areas to avoid. It very regularly strays several meters beyond the limit I had set.
Some of the better wireless ones are using lidar or additional sensors, but those options all cost more than a simple wire signal detector.
