Do you have a folding knife that you like? If so I agree with
@carnifex knifeworks and suggest that you skip the small fixed blade for now. A pocket knife can do 99% of Mora work.
Check out the Silky Nata 150 and Becker BK7/9.
You can also find lightly used Swamp Rat and Scrap Yard knives within your budget. Check out this subforum:

The larger Res-C handled versions are very lightweight for their size and are extremely comfortable for chopping.
