Well, you have to define "fun".  For 35 years most of my macro work was done 
with my Rollei SL-35, a bellows and a Zeiss 135/4 Tessar lens.  Worked just 
fine.  A bit of a bother because you have to do two lens mountings.  Attach 
bellows then attach lens to bellows.  If I had owned a dedicated short mount 
lens for the bellows I would not have to release the lens each time I needed 
to use it.

When I went to Leica in the late 90's, I bought a bellows with the 100/4 
Leica short mount macro.  That is what I was use to.  Worked fine.  Needed 
to replace the cloth bellows once.  That was not a big deal, just ordered a 
new owe from Novoflex.  Then an opportunity came up to buy a 100/4 macro 
lens with focusing.  Did that.  Not sure why.  Same quality as the short 
mount.  Indeed, the same lens I think.  I found it limiting since it did not 
focus 1:1, or even 1:2.  Sold it.  Then I bought the 100/2.8 APO Macro.  No 
looking back.  Have the 1:1 Elpro, too.  Wish it focused all the way from 
infinity to 1:1, like the short mount on the bellows, but optically, no 
comparison.

Sold the short mount but kept the bellows for ultra close-up work.  Slap my 
50/2 with reversing ring and can really get close with good results.  Never 
measured it, but perhaps 2 or 2.5x.  Not as sharp as a luminar or some such 
ultra close-up, but it gets a shot if needed.  I had though I could mount my 
100/2.8 on the bellows, but it will not mount.  Novoflex says I could update 
the mounting flange for $150, but decided not to do that.  I did not know 
the ROM mount is different than the non-ROM mount just enough it will not 
work on my old Novoflex bellows built for the R4.

If you can get the bellows for cheap, use existing lenses, it is a good 
option.  Or find a nice old short mount macro lens.  If you want to go 
beyond 1:1, then they are great.   I do fine a dedicated focusing macro more 
convenient.  It is certainly sturdier.  That bellows hanging out there 
always scared me.  I was afraid I would crimp it  or damage it somehow.  And 
when it was raining I had to be sure to protect it and wipe it down good, 
store it open until it was very dry then collapse it.  I didn't do that once 
and it was stuck.  Had to very carefully pry it open.
