I use Miguel in Roquettes.Good guy,speaks English and gives you the old parts back.Gives you plenty of options for parts depending on budget.

Once got charged €140 for a service on a lawnmower from the place opposite the park.Took it in for a new cowling underneath near the blades and picked it up 3 weeks (he said 3 days) later.No cowling but bless him,he's done a full service 2.5 hrs work......takes me 20 minutes.Prior to that I'd spent a lot of money with this guy.Not anymore.
