Check for them on sites like J&P, Dennin Kirk and such. Easy connecting, but suspect apperance and sub-par quality, I fear. I spent major bucks and got the factory option Harley original and am happy with it on my '08.

Koso and HD. Koso has some cool features and mine works well on the 07 sporty.
I like my HD (13 Dyna) one better than the Koso. Neither are what I would consider cheap. You could try a cheap hour meter, spark plug deal too.

I use a clip on tach to set the idle and the 2000i has a rev limiter. I call that good enough for me, but I have concidered a small shift light so I know when I'm aproaching the rev limiter.

I suppose it depends on what you want out of the part you fit with appearance to the rest of the bike.
I went with the HD offering as it doesn't detract from the rest of what I have and is a single unit showing analogue tachometer and digital everything else. Plus with the costly extra bit I also get a fuel gauge.
Possibly best for bikes '08 and newer due to changes to what's programmed in the ECM.
70900100C - 4 in. Combination Digital Speedometer/Analog Tachometer (HDI)
70900475 - Domestic
61200008A - Fuel Sending Unit
70900274 - Combination Digital Speedometer/Analog Tachometer for '04 to '13 Sportsters
The USA model can display miles or kilometres so I really don't know what the difference is between 70900475 and 70900100C but these are the ones for 2014 and newer.
