well, I don't know about the A100, but my very first handgun was an Astra A80. The slide stop broke after putting less than 50 rounds downrange. After 6 months, it came back from their warranty dept.....and it broke again inside of another 200 rds, this time the hammer snapped off. The shop I bought it from was really cool--They bought the defective POS back because of all the trouble I was having with it.
If price is an issue, I would recommend the Taurus or an EAA Witness. If you can swing a couple hundred more bucks, I'd say go with a Beretta, Sig, Glock (ugh), XD (double ugh).
ANYTHING but an Astra.
