$29.29 LCD Digital Thermometer DT-300
this is a cool voltmeter that plugs into your cigarette lighter and will tell you instantly how your battery is (with car off) and how your alternator is performing (with car on) - $2.81 to your door! 
- how can you beat that, diagnostic answers without even cracking the hood! (it takes about 10 days to arrive from Hong Kong so be patient)
also, every owner of a 95 and newer Lexus should strongly consider this $17 OBD-II diagnostic code scanner that works great! - that price is just insane!
I own both of these and they are some of the best buys of 2013
PS - before you laugh at the $2.81 voltmeter, I will tell you that I checked it against my $400 Fluke 87 series V multimeter and it is spot on!

I found the company also sells http://www.ebay.com/itm/LCD-Digital-Thermometer-DT-300-MIn-Non-Contact-Infrared-/390567707606?pt=US_Weather_Meters&hash=item5aefa643d6 and I ordered it together with another voltmeter. The payment was still less than $33 to my door.
While ago those arrived and I just checked the thermometer. The 4 measuring results below are from my wife's car Toyota Avensis which is not common in USA but rather common in Japan, Europe and Oceania. She just came back from the shopping and the engine was at a warmed up condition. The thermometer also indicated 36.3 degrees C when I measured my wife's ear. I'd say it's accurate enough for a Sunday mechanic like me.

do you have a nice infrared thermometer to compare the accuracy with, like you did on the voltmeter with your high end voltmeters, side by side?

I don't have any more infrared type but I have a 3 digits digital thermometer which detects temperature using an external sensor shown below. This shows just 100degrees C when the water is boiling up at 1 atm condition. But it only has 3 digits. Anyway I will be comparing them soon.

I wanted to measure and compare these two when the water is boiling up. But too much moisture disturbed the measurement. I stopped heating and waited a couple of minutes and then measured again. The result was 87and 86.9 degrees C.

Many UCF20/21 models for non-US market is not OBD-II compatible, I am afraid.
My 98 JDM does not communicate with a LM327 code reader at all.

Yamae san, is there an affordable code reader that I can buy from Japan to read the codes on JDM Celsior? It would be something nice for me to have since my current obd 2 reader is useless.

JDM UCF20/21 and early version of UCF30/31 need a special scanner called a S2000 which costs more than 300,000 Yen (about $3,000). You can find the detail of it at here.

There are some others but those cost more than a S2000 according to shop owners I know. One of them bought a HDM-3000 below. He paid more than 500,000 Yen for it.
