The jump range on a vanilla Asp is fine, really. It's just less than an engineered one. Once you get used to the engineered FSD, the old one seems low.
If you spend the extra $30 to upgrade to Horizons, you can unlock engineers easily. I did this tonight. I needed 50 Lavian Brandys, but Lave was only putting 6 out at a time with a max of 12. I got the 12 in my alt account and took my original to Lave. I picked up 12 and transferred them to my alt and repeated until I had plenty for one trip to unlock. I fly 2 CMDRs on the same computer at the same time. I also "rescued" myself once when I ran out of fuel.
$30 isn't a lot to spend. I'd be willing to bet that you spent more than that on your controller(s) or even this week's McDonald's runs. It's the price of 2 good cigars or 1 really good one. Worth every penny.
All 4 of my CMDRS have Horizons. It opens up options that become more evident as you go along. Give in to temptation. To do otherwise will just lead to frustration.
