I am not a fan of security splits, however if with the right management they can retrace the price to old highs then its well worth it. Look at TOL, they are wealth accumulators and have benefited sharholders who have continued to stick with them. CHO it seems to be heading in the right track.
brka refuses to split its shares for the reason you stated. However they did introduce brkb for those a holders who want to sell not the full amount of Berkshire they own. brkb is 1/30th the price.
I think brkb is well worth the investment.
