Given the current stock level situation, it might be better to put the money aside and wait for fresh supply of stock to come and hopefully for logistics issue in Japan to return to normal.
This might also be a good time to get from the bns section or visit some of the 2nd hand shops in Peninsular and Adelphi to see if there are older models since the difference in technology is not really miles apart. More importantly, photography is not all about using the latest technology ....
Just wait for the new stocks to arrive if is not urgent. Some shops are marking up prices. Save up the money first. Don't let them benefit.
