I have an Acer Aspire 5 which I bought at the beginning of last year, and am very happy with it. (Still on Windows 10)
Before that I was using a Lenovo, and initially I was quite happy with it - so much so that I encouraged my wife to get one too. However, the second one was a bit of a lemon and had some power/battery management issues, so we got a refund on it. She then chose an Acer, and as she was happy with it, in due course I got one too. My old Lenovo is still going as a spare, but that might now be developing power issues too.
The amount of storage might vary according to what kind it is. A traditional disk drive (HDD) may well be 1TB, but SSD's cost more so are typically less than that. SSD's are faster, and I thought it was worth compromising on size to go for one of these. Mine has 500GB and I expect that to be plenty, but if not I should be able to offload some lesser-used things to an external drive.
If you're already using 180GB, and there's a chance you might keep this laptop for 7 years, I'd suggest that you aim for 500GB too (or more?). Any new software you get in that time, plus more scans or bigger file sizes, will all want a chunk of your drive, and 256GB may not give you much leeway.
