The auto MCACC is great, but the deals available on the 43TX right now make it very attractive.I second that. The auto MCACC is great, but look at the price upgrade to the 53tx for that feature..., my opinion, but I wouldn't pay for that. Stick to the 43tx.
Most places were advertising for about $200 more for the 43tx before it's discontinuation. It's a steal.
