I have to agree, after having servicing and repairs done by garages for 20 odd years I decided to give it a go this year myself, apart from the savings ( about 80 percent) I really enjoyed it, was gutted when I'd fixed and serviced everything I could think of, could do with a scrap car just to fiddle with! Seriously though, took me about an hour too, back ones are fiddly but easily do-able , you have to remove the coils to get to the plugs, so again, very easy, plugs cost £16 for 8 on eBay.
