I own both and the Opus isn't even in the same league as the MC3000. If you don't have the cash the Opus is fine but if you want the best pay up and get the SkyRC, it will more than likely be the last charger you ever buy.
If you want the MC3000 for $80 email Robert stating that and give him your zip code. He will add on the actual USPS shipping to you and then send you a paypal invoice. He will ship it out the next day. This price is not available on his website or Amazon store or is it advertised. It is a special created for forum members. The chargers are the latest production with all the improvements.

Now you may be able to save a couple bucks ordering from one of the China Ebays but Robert ships out the next day so you get the item in 1 to 5 days depending on which coast your on instead 3 or 4 weeks, the mfg warranty is thru him here in the good old USA and you can reach him any time on the phone for questions or problems. It's a no brainer for me due to the warranty. If you buy from China and anything happens you have to send the unit back to China and the shipping is typically more than the item plus you may get it back in 6 months!
