IMHO you will
NEVER be a serious & proper brewer until you learn how to master the process, the process, the process.
I might be seen to be blowing my own trumpet, but I got into AG brewing long before March pumps (or any other pumps), grain mills, or even BIAB arrived in Oz & happily lived with a bodgied-up 3-vessel gravity setup (& less) until the aforementioned arrived & were available.
You young farts can thank your lucky stars for the multitude of brewing options you now have at hand in 2014 going onwards into the future.
After about 9 or 10 years of use, my SS HERMS still gives me much pleasure but I could/might/perhaps/possibly consider rolling over to a 50-litre BM if I win the Lotto one fine day & when I find I can't tie my shoe laces anymore.
Would never even consider getting a 20-litre BM because of its limitations & apologies to those who have them if I've upset you.
Each to his own I guess?
PS ---- I must admit that my HERMS costs over the years have probably racked up close to 2\3 of the dollars needed for a 50-litre BM purchase & that's building to a (tight) budget stretched out over quite a few years with not too much bling, but repeat that my expenditure was slow & steady compared with an up-front cost of a BM.
Just my 2-cents & input. I'm sure I'll get lots of nice responses?
