Hi all,
I agree with the sentiments regarding the BM6A`s, they are damn fine studio monitors, HOWEVER if you have less than the perfect monitoring environment such a set of monitors will be going to waste (partially) and offcourse if you are on a llimitied budget then they are out of your reach.
I also agree with the sentiment above that you should not short change yourself on minitors, but again the monitoring environment come sinto play - No point spending £2k on monitors if they are set up next to a window in a living room of your house

So my perfect procedure would be as follows.
Get a new house which has a basement (completely concrete room

Get Large Bass traps, Corner sound absorption Wedges and sound defraction tiles
Spend a week or so setting up your perfect monitoring environment for your new monitors
Then make some cool music.
OH WAIT A MINUTE !!!
Now that you have those shit hot monitors and perfect monitoring environment you will need to spend mor emoney on a top of the range soundcard with high end AD/DA convertors

:P
HAHAHAHA only kidding, limited budget and restricted space are the only things that matter in this scenario so in this case these are what dictate the monitors you buy.
Goto the top end of your budget, look for about 5 sets of monitors around that price range, check for freq response and RMS output. Also look for monitors with room acoustic settings on the back which allow you to adjust for difficult set up positions.
The
Behringer Truth B2030A fit the bill quite nicely
