I stand by my post. When you're just beginning to learn something and you don't have anything but very basic equipment and you don't know if you're even going to like doing it, there is nothing wrong with making a simple product from scratch for yourself
In my opinion, if you want to make a cream it probably means you have a blender/stick blender at your disposal, at the least, which along with a scale should fall under the basics for lotion making in my opinion...and if you can afford ingredients for a cream, I don't really see what's stopping anyone from investing in a scale. Especially when you can get them for rather cheap from ebay.
Here's (one of) the ones I use:

Here's one that weighs up to 300g at a time:

Both are just over 7 bucks, so in my opinion, even if you don't think you'll continue after your first bacth, it's not that big a loss ( and you can always use the scale for other things). You may wan to invest in something sturdier later on, but for a beginner this works.
If you don't have a stick blender, you can make small batches (up to 100g, though I've pushed it to 200g at times) of light creams (so light on the butters) with a cheap milk frother you can get at Ikea or dollar store type shops.
I also feel like the "everything natural is good" train of thought is kind of a fallacy (just like the "everyhting synthetic is bad" thought).
E.g. cadmium... you deheeeefinitely dont want that on your skin or anywhere near your mouth (I wear gloves when I paint with oil paints containing this).
And if preservatives scare you because "nasty chemicals", I think these days you can also find ECO-cert preservatives, which seem to be a lot less agressive etc. (e.g. Leucidal and Natapress), though they do have a shorter shelflife and are slightly more difficult to work with.
But this is why I'd advise beginners to stick to anhydrous products first (for the longest time I was intimidated by preservatives/emulsifiers etc. too).
You can make a pretty awesome whipped body butter using some lighs oils, butters and a handmixer.
