A really nice new lens on your budget would be the Tamron 28-105/4-5.6 or the Tokina 28-105. Both are terrific values for the money. The Tamron is nice and light and a really decent performer.....generally around $150 or so new (I paid $158 for mine). The Tokina is heavier and a better build, and a bit closer to the $200 mark I think, but an excellent lens. Both of these are autofocus lens, ideal for the ZX-5n.
I've heard nothing but bad things about the Sigma 28-105/2.8-4...not real sharp, poor contrast, not a very highly rated lens. The Vivitar has been rated both as generally pretty good, or generally pretty lousy..depends on whose review you look at! The FA28-70/4 is outstanding! It is a bit slow but if you go with the new 800 speed films, you just might be alright. A really good lens in the 28-70/2.8 category is a used Tokina, but these are probably a bit over your budget...they seem to list and sell for around $235 or so in good condition.
