Thanks for all the comments, interesting to see everyone has different views.
I think I've ruled out the Makita, wasn't keen on it to be honest and some reason felt a little underpowered when I had a go of it. Anyway, everywhere seems to have them out of stock. Looks like the Bosch is OOS too form FFX and loathed to pay upwards of £70+ from other sites as I can wait.
After a little more searching, I think I am going to go for the Mafell as I feel the price will be worth it and likely last me a good while. However, after reading Doug B's comment, I've been looking at the cordless version too. Currently, my workshop is outside in the garden until I get round to getting a shed built after house renovations - probably end of the year maybe longer. I wonder if the cordless makes sense over the corded in the longer term? I have outside plug sockets so corded is not an issue for me right now but may be when the shed is built. I don't generally use dust extraction outside when cutting either so if dust bag collection on the cordless Mafell is any good that could be a plus point -
@Doug B any comments on that?
Also noticed the cordless only has one speed, unlike the corded version - are the speed settings just a gimmick or do they actually come in handy?
I am not in any rush to get a plunge saw, so I could wait another month if you guys reckon cordless is a better option or would i just be wasting money. Would probably look at bare unit and get Metabo batteries and railes separate. If not worth it, I might as well go and get the corded Mafell this week.
Thinking about it, I supposed that would bring the Bosch blue cordless plunge saw into play (GKT 55 18v GC) slight cheaper than Mafell, not heard good reviews on that tho.
