Aircraft Choice delemma

I have an interesting decision to make. I'm soliciting opinions and
your perspectives.

I have a nice Beech A36 Bonanza. It is a 1980 in good shape. 3000
hrs ttaf, 575 smoh, I am second owner, mostly origional style avionics
(KNS80, ARNAV GPS, Argus 5000, WX10, King coms, nav , and ADF. It is
a nice stack that I am quite comfortable with. I like a RNAV, since I
file RNAV direct and fly the GPS. Mo databases to buy to be legal
IFR. It seems that the King hardware is taking more and more to keep
it healthy. I usually make 2 trips to the avionics shop per year for
something. Com radios have been somewhat troublesome....Last month it
was the glideslope receiver. Fortunatly both were minor repairs this
time.

The plane is getting dated with respect to paint and interior. It is
OK, actually looks pretty good, but still there are nicks, chips, 1
minor dent (a small bird), and some staining. A solid 5/10. Interior
is good too but the fabric is 1980 style and the leather interiors
look, smell and feel sooo nice...

If I were to invest 25K in paint and interior, 30K in avionics it
would be as nice as a new Bonanza, call it 50K for round numbers.

I can comfortably handle the maintenance, annuals, and operating costs
of the A36. The plane suits my missions perfectly which are often
2-5 hr XC trips with usually 2 on board + some cargo. I fly mostly
for personal transportation and 20-30% business related travel. I can
usually adjust my schedule to avoid rough weather (ice, squal lines,
and heavy storms) and deal with the rest.

I can get into a same vintage Barron (58) for my plane and 50K. The
one I found has 2 430's, fresh boots, 300 hr engines (550's) but
highter time ~4800 ttaf, fresh paint and interior.

There is a lot of hardware on a barron that takes care and feeding. I
think that I can handle the operating costs, but worried that the
maintenance could overwhelm me. I do a lot of it myself, even the
annuals with proper supervision and signoffs. Still, there is a lot
more to a twin.

I have not checked into insurance yet. If the hull values were close,
would there still be a significant premium for the twin? I do have my
ME and get re-trained every year, but my twin time is less than 50
hrs. Almost 1100 flight hrs on me.

Comments gentlemen?
