Which nailgun?

[scott b]

I am about to refurbish our new house and have a fair bit of internal work to do. I want to re floor board several of the bedrooms and will be leaving them as bare boards (although varnished) and do the usual skirting boards and architrave as I go through the house. I have an air compressor an wondered whether a brad nailer would be suitable for what I want or would the brads/nails not be strong enough etc.
From looking at them most brads are 1 - 1.5mm. I was looking at the makita AF505.

Is this suitable or does anyone have any recommendations for a decent air nailer under £100.

Thanks

Scott
