Plastic shed - yes or no?

Hey there,

I've never had a garden nor a shed.. I want to make sure I choose the right one, but clearly I need help.
After spending days and days and days... online looking for a shed I've narrowed it down to 2 options -a 6ft x 8ft wooden shed OR a same size plastic shed. The price is almost the same, however I was told by a gardener, that a concrete base would be needed for both since my garden is new and very soft. The concrete base + building up the shed would cost 1,500 EUR. A bit pricy for me, but maybe it is the regular price for concrete base + labor.

Pro & Con wooden shed:
* looking nice
* annual maintenance
Pro & Con plastic shed:
* no maintenance needed
* no window on the side and grey

I have a disability and I won't be able to paint the wooden shed annually, I would need to pay somebody to do that.

Question:
* does anyone have a plastic shed? If yes, what is the experience so far?
* Ireland (Portlaois to be specific) can be rather windy. Would the plastic shed "survive"?
* do you know if the plastic shed could be painted (to add some nice touch to a grey shed)?

Thank you very much for any help and advise.
