Yes, best bet is definately to Clone Jump when you feel the need for some Pew Pew... then jump back 24 hrs later no harm to the implants.
You can install some plus 3's if you can't bare to loose all your training bonuses, but they are still not too cheap.
If you haven't already get infomorph phsycology (however it's spelt) upto about 3 then you can have two or three copies of you in different stations dependant on the measure of risk you anticipate, you can have plus 3's in one and none at all in another if they have high risks... You can spread your clones out accross new eden or have them all in the same system (different stations though)
If your corp doesn't have the standings to allow you to purchase said clones (you only have to buy them once, unlike medical clones of course), there used to be a corp that you could join that basically was there just to provide jump clones, you joined up, bought your clones and then left again... Can't remember what it was called explicetly but it was something like "Estel Arador" don't know if it's still around.
I may myself eventually bite the bullet and train up to lvl 5 so I can get one more JC, they are invaluable for me to be able to jump to my missioning clone when 0.0 is too hot to get out or if I need to get out to raise funds.
