A 510 is weaker than a KR808D-1 but if they really want something that looks more like a cig, a white manual 510 used with the tan or white Boge 3 ohm blank cartomizers from NiteLiteVapor.us will give that look.
I recommend Joye/Joyetech brand (and if you don't get joye then definitely do not get FS510 - reverse electrical polarity)
Cignot.com lists the LED and battery color but may add their logo to them. LiteCigUSA.net has them.
Get a 510 drip tip (the plain clear color ones at LiteCigUSA.net do fit Boges and the atomizer but I found most some others there too tight. Use drip tip on atomizer to test juices, and on carto as an easy to remove mouthpiece if you want (make it easier to check stuffing and add liquid).
Get Eliquid (I do not recommend high VG with Boges. I use high PG juices like 80PG/20VG and the clearest juices will let the cartomizer ladt longer. Keep cartos DAMP to avoid singeing. I can get 10 days use out of a Boge)
And as I said, NiteLiteVapor.us is the only place I have seen the standard resistance (around 3 ohms) Boge cartomizers in white and tan. Everywhere else just has black or steel. And slim 510 should only use cartos 2.5 to 3 ohms. Anything lower is not for slim batteries and can damage them.
I found as soon as I started vaping that I did not want it to look like a cigarette. People don't like smokers - why look like a smoker. I prefer the black 510 manual w/ blue/purple LED and black Boge cartos.
